numpy中的局部均值过滤器

Question

I have a 512x512x512 numpy array. Is there any efficient way to perform a mean filter where every array value is substituted by all 3x3x3 local values?

We are seeking somethin similar to scipy.ndimage.filters.median_filter but insted of median with mean.

Answer 1

scipy.ndimage.filters.convolve()权重： np.full((3, 3, 3), 1.0/27) 。

Answer 2

mean filter 是uniform filter的别名，可以在scipy.ndimage.uniform_filter中找到。
